feat(ops): implement fast lazy async ops (#16579) Implements fast scheduling of deferred op futures. ```rs #[op(fast)] async fn op_read( state: Rc<RefCell<OpState>>, rid: ResourceId, buf: &mut [u8], ) -> Result<u32, Error> { // ... } ``` The future is scheduled via a fast API call and polled by the event loop after being woken up by its waker. 2022-11-11 08:44:53 -05:00			`=== Optimizer Dump ===`

perf(ops): Reenable fast unit result optimization (#16827) The optimization was missed in the optimizer rewrite https://github.com/denoland/deno/pull/16514 2022-11-26 23:48:17 -05:00			`has_fast_callback_option: false`
fix(ops): disallow memory slices as inputs to async ops (#16738) In Rust, it is UB if a slice is mutated while borrowed except through the slice itself, and it is also UB if a mutable slice is read while borrowed. The op macro allows borrowing an `ArrayBuffer{,View}` as a memory slice for the duration of an op, but this is not sound for async ops, since the `ArrayBuffer` could be accessed from JS during the await points. This PR therefore disallows such automatic borrowing only for async ops. Co-authored-by: Divy Srivastava <dj.srivastava23@gmail.com> 2023-01-15 02:40:01 -05:00			`needs_fast_callback_option: false`
